    <!--
        封装一个组件 HmButton
        给自定义组件注册 原生事件, 默认是无效的!!!
        (原生事件click change..只支持添加给网页元素div  span)

        1. .native修饰符 作用是给组件的根元素添加原生事件
        <HmButton @click.native="handleClick" />

        2. 组件内部做一下支持(给button添加原生事件, 事件里面触发自定义事件click)
        <HmButton @click="handleClick" />

       结论:
        如果你用的是别人的组件, 且你想注册原生事件, 成功了 => 别人组件内部做了支持;
        失败了, 加一个.native
